The pressuremeter was introduced to North America by Ménard in 1957. It consists of a cylindrical probe which is inserted into the ground in a borehole, by self-boring or by pushing, and is expanded against the soil or rock to obtain a pressure-expansion curve. Interpretation methods based on cavity expansion theory applied to realistic model...
View ArticleThis paper presents results of the instrumentation of 373 blows from two SPT deployments performed in the Sarapuí II Test Site, located in Duque de Caxias, Rio de Janeiro. In these blows the hammer drop height, its velocity at impact, the rate of blows and also the energy transferred to the rod stem have been measured. It is therefor...
View ArticleComprehensive research has been carried out by the Geotechnical Group (GEGEP) of the Federal University of Pernambuco in the soft clay deposits in Northeastern Brazil near the city of Recife. This paper presents the results of important geotechnical investigations of soft clays in two areas within the Suape Port and Industrial Complex. The geotechnical ...
View ArticleLarge-scale mining operations generate vast quantities of tailings that are deposited in hydraulic-fill tailing dams in the form of slurries. Stability of these impoundments require investigation of water table configuration, aquifer boundaries, site characterization and determination of short and long term properties of tailings. These aspects are eval...
